This is the worse thing that can happen to a friend ship.... normally ends up in an awkward situation. having said that this is not always the case.
Be careful, as even though u get the feeling that they like you, it can not always be the case.
I would think to myself what i would gain if i was to enter a relationship with them, and what i could loose at the end of it?
They say love is like friendship on fire, and since friends last alot longer then the average dating couple (specially at your age) maybe friends would be better.
But then again, I'm not totally sure how you, and they feel, so i can't way everything up......
